RADIATOR coNnnNsEn.

Application led December 4r,r v1926. Serial No. 152,605.

My present invention relates to an im proved radiatoi` condenser for use with the radiator of the water cooling system of thcl internal combustion engine used on auto motive vehicles.

As is well known alcohol and other anti* freezing agents are used in the water cooling systems of internal combustion engines for automotive vehicles, and the primary object of my invention is the provision of a con denser used in connection with the radiator and its cap for condensii'ig the evaporated alcohol or antidreezing agents, as well as for condensing the evaporated Water of the cooling system. By condensing the alcohol and water and returning the condensate to the radiator, I economize in the use of both Waer and the anti-freezing agentin the cool` ing system.

The device of my invention provides a cmnpact, integral structure which may be fashioned as a casting, and the casting may readily be applied to the radiator, and with equal facility may be removed therefrom when necessary. In addition to its utility in exposing and dissipating the heat from the vapor that may be produced .by excessive heating of the interna-l combustion engine, the device of my invention also provides an ornamental accessory for use with the radiator.

The invention consists in certain novel combinations and arrangements of parts as will be hereinafter more fully set forth and claimed.

In, the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged according to thebest mode I have thus far devised for the practical application of the principles of my invention. i

Figure I is a View in frontelevation of the device of my invention.

Figure II is an enlarged vertical sectional view of the device of Figure I.

Figure III is an enlarged detail sectional View showing the vent of the device.

In order that the general arrangement and relation of parts may readily be understood, I have shown in FigureI a portion of a radiator 1 as customarily used in the water cooling systems of motors for automotive vehicles. In converting these radiators for use with my invention I utilize the nipple 2 having internal threads, and the oversflow pipe 3 usually provided for the radiator is closed with a plug el..

The condenser of my invention is preferably cast in a single piece, andcomprises a cap 5 having an exterior threaded flange 6 adapted to screw into the nipple 2 of the radiator. The cap in its upper portion is fashioned with a dome T to receive vapor from the water or other cooling agency in the radiator, which may be generated by execs sive heat from the motor or engine.

Above the dome are arranged a plurality of (por pipes, two of which are indicated as 8 an 9. These pipes are integral with the dome and at the upper ends of the pipes is fashioned a condensing chamber 10 in the form of a hollow sphere. The vapor pipes of course communicate with the interior of the condensing chamber, and these pipes convey the vapor to the chamber for condensation. y

The iater oil condensation or the condensed vapor from the anti-freezing agent is returned to the radiator through the return pipe 1l. This pipe comnn'inicates with the condensing chamber at its central lowery most point, and the lower end 12 of this return pipeprojects down through the radiator cap with its outlet end submerged below the water level in the radiator.

- Ventilation is provided from the interior of the radiator through the vent .pipe 13 which has a port 14 opening into the return pipe 11. Thus should the water level rise excessively, the water may pass directly through the pipe 12, a portion of the pipe 11 and thence upwardly through the port 14 and outlet pipe 13.

In Figure I the cap 5 is shown as fashioned with the usual pair of handles 15, and wings 16 are shown as ornamental features on the exterior of the condensing charnber `10.

While I have herein shown and described one oxempliiication of my invention, it will be understood that changes and alterations maybe made therein, within the scope of my claims, without departing from the principles of my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination Awith a radiator, of a cap forming a vapor dome, and means for securing said dome to the radiator, a closed condensing chamber spaced above the dome,

e vapor pipe connecting said dome and chamber, a return pipe communicating with said chamber passing,r through seid dome and extending into the radiator, und an overfiow pipe having a port in the return pipe between the chamber and the dome.

2. The combination with :l` radiator of a condenser comprising an ntegra] member, said condenser including e vapor dome, a

spaced spherical condensing chamber above said dome, a, plurality of vapor pipes connecting said dome and chamber, a single return pipe connected to seid chamber and A )assino throuffh said dome and an overow pipe having a port in said return pipe.

In testimony whereof 1 affix my signature.
